To aZZvw/"Lom t may concern.'

Be it. known that I, JOHN C. HUMMER, a citizen of the United States. residing at Flemington, in the county of Clinton and State of Pennsylvania, have invented new' and useful Improvements in Combination Tire-Tools and Lifting-Jacks, of which the following is a spcification.

This invention relates to newoand useful improvements in tools and the principal object of the invention is to provide com# bined tire tool and lifting jack.

Another object of the invention is to provide a jack provided with pivoted jaws at each end, thereof for engaging the rim of the tire.

Another' object of the invention is to provide a'device of this character which is simple and durable in construction. reliable and ecient in operatioi'i,l and one which can be manufactured and placed upon the market at a minimum cost.

The invention Aalso. consists in certain' other features of construction and in the combination and arrangement of the several parts, to-be hereinafter fully described, illus trated in the accompanying drawings, and specifically pointedfout in the appended claim.

In describing my invention in detail, reference Will be had to the accompanying drawings wherein like characters denote flike or corresponding parts throughout the several views, and in Whichz` Figure 1 is an elevation of the tool with parts broken away, ,a

Fig. 2 is a view of one end of the device.

Fig. 3 is a view of the other end of the' device, and l Fig. 4 .is a cross-section on line 4,4 ot Fig. 1.

As shown in these views the device comprises'l the base member 1 having the rec-A tangularbase '2 and provided with a, eentral opening-through which the Worm member 34 passes. 4 isthe top member provided with theelong'ated head .5 and having' a screwthreaded bore for receiving the worm member 3.

Tle wornrmember 3 is provided with a collar 6 'against which abuts the hub 7 of. the toothed wheel 8 which is suitably connected `as by a spline with the worm member 3. A hand lever 9 is connected with/a ring l@ which loosely surrounds the smooth part -by the member 3.

of theworm member 3 and said ring is held between the wheel 8 and a collar 11 carried 'A double-headed dopY 12 is pivoted tothe handle 9 by means ot' the bolt 13 and is adapted to engage with the wheel 8 so that the said wheel may be rotated in opposite directions by reversing the position of the do;r on the handle. The base 2 and the head 5 are each provided with a pair of ears 14 at each end thereof, betweenwhich are pivote-d jaws or hooks 15 which are adapted to engage the edges of the ordinary split rim of attire so that the same'may be contracted by operating the jack to move the parts thereof toward each other. I

If it is desired to expand the rim. opposite parts thereof are engaged by the base 2 and head 5 ot the jaclgmind the handle is moved to force said parts away from each other and thus expand the rim.

The partwt of the ,iaclris-provided with a foot 16 'sothat the Ajack ma)v be used as an ordinary lifting-jack. hooks or.ja\vs may Lbe swung' inwardl)V or said parts ma)v be removed. Ot' course. if desired. the head 5 may eugafge the part to be lifted instead of the foot 1G.

It is thought from the foregoing' desaripv tion that the advantages` and novel features of my invention will be readily lapparent.

I desire it to be unders-.toml that l may make changes in the construction and in the combination and arranjwmeut ot' the sevlral parts, provided such changes fall within the scope of the appended claim.

A device of the class described. comprising a base parthavine an enlarged base and a plain bore. a movable part having` an elongated head and a screw-tlneaded bore. a t'oot on bthe inner end of said movable part. a. worm memberpassing` through the bore in. the base part and engaging' said screwthreaded bore of lhenovablefpart. a toothed wheel secured to said "gvorni member. a col-l lar on said member buttinggthewheel. a
